An Austro-Hungarian standard during World War I, the Schwarzlose 1907 machine gun was used by the infantry, in fortifications, and as aircraft weaponry; due to issues with adapting the weapon to synchronization, it was sometimes deployed in a detachable, wing-mounted container that was essentially the forerunner to the modern aircraft gun pod. At the end of the war, the various successor nations of the Austro-Hungarian Empire kept using the Schwarzlose, with a significant number of them being used to arm the Czech border fortress system during the lead-up to World War II.
